[ovirt-users] Data Center Compatibility version

So I updated our environment a bit ago during a scheduled down time from 4.2 to 4.3. Everything went smoothly, but it looks like I forgot to update the Data Center Compatibility (See alert message below). My question is, can I just change the Data Center compatibility to 4.3 while the environment is running without causing issues, or do i need to shutdown all my VM's and put the hosts into maintenance mode? The compatibility version for everything else is already set to 4.3. Thanks Alert Message: "Data Center compatibility version is 4.2, which is lower than latest engine version 4.3. Please upgrade your Data Center to latest version to successfully finish upgrade of your setup"
